There is also Recycle move too, not just Harvest. Also, the Pokemon with Harvest are decent at best only, so I would suggest avoid using them unless you really want a Pokemon with Harvest. Do note that Harvest works 50% of the time in normal or any other weather condition aside from sun, 100% of the time in sun.
